I had bought one of the foam sleds at local big box store before a recent snowstorm, and the kids fought over it. So I snagged one recently on Woot for MUCH less than big box, and it arrived during the next snowstorm (thanks UPS guy for delivering during our paralyzing snow!).
Kids love it more than the plastic saucer style, and it's more durable than I expected for being so light. Works well in shallow snow like we get here in the southeast. Definitely a worthwhile buy even if you don't have tons of snow!
